Abstract

Cadre de filtre (34) étant un cadre à quatre côtés constitué de deux premières parties (35a) disposées avec un espace entre elles dans une première direction et deux secondes parties (35b) disposées avec un espace entre elles dans une deuxième direction, et comprenant une partie en forme de cadre (35) pour maintenir les bords extérieurs d'un filtre, de premières nervures (36) qui relient les premières parties (35a) l'une à l'autre, et de secondes nervures (37) qui relient les premières parties (35a) l'une à l'autre et sont disposées avec des espaces entre les secondes nervures et les premières nervures (36) dans une troisième direction. Une partie d'ouverture de filtre (41) est formée dans l'une ou l'autre des deux secondes parties (35b). Un espace pour placer un filtre à l'intérieur est formé entre les premières nervures (36) et les secondes nervures (37). Les premières nervures (36) et les secondes nervures (37) sont formées pour être déformables entre un premier état pour pouvoir serrer et maintenir le filtre, et un second état pour pouvoir être séparées du filtre.
